TO A-LL WHOM IT MAY GONCERN v Be'it'known that I, CHARLES SAYWARD, ofGloucester, in the county of Essexznd State ofMassaehuSetts, haveinvented certain new and useful Improvements in"Gudgeons for Booms'gfendl do hereby deelnrethat. the following isna full, clear, andex'actdescription of thesnme, reference being had to the accompanyingdrawings, making a. part of this speeieation. Y l t Figure 1 is avertical section.

Figlire 2` is 'a horizon-tel section'.

Figure S'shcws-eipetented article and its objectioneiblefeature. l

.The object of my inventioni is yto obvintethe objections experienced ingudgeonsvfor booms 'as at present patented, and` to provide n-mthod ofattaching the boom to the.nies t,"so that it can readily move inganydirection about its attachment.

In the patent of AMr.Robbins, dated 4July 9, 1867, he has `shownahorran-gement `by which the boom is hinged to a. block, through'whicha. pivot passes, saidpivot being attached to al gudgeon, through whichthe vp intle passes whichconnects the whole with the roest.Y

It is found hyactualobse'rvation, that when a vessel is put before thewind the boom turns upon 'the pivot i to such :in extent that the wholeattachment is deranged and doubled up, ns shown in iig; 3, thusyentirely destroying its utility. s A,

In my invention,4 I`plaee the port bearing-the pirot Ain directconnection with the boom, and pass the pivot through the p'art'gl3w.hiohis Vhinged 4to the yoke C, which yoke turns upon the pintleD.

By this arrnngement, Iy make it impossible for the several parts toperfo'rnr other than their intended fonct-ione',viz,that the boom willhave a swivel motion and' a. motion up, down, or sideways, esmny berequired,

and that it may have n farther upward and downward motion 4upon thepintle.

I om awel-e that the combination` shown in my description is old,andtlierefore do not claim it, but wish to eonne myself to thearrangement cf the parte eornbined, viz, having the swivel, nnd'not Athehinge, next the boom.

Havingthusdescribed my invention, what 'I-elaim as new, and desire tosecure by-Letters Patent, is

The arrangement of the swivel, hinge, yoke, o ,nd bolt, the Swivelintervening"b etween the boom and the hinge, substantnllyns and for thepurpose specied. ,Y CHARLES SAYWARD,
